Battery is completely dead and phone wont charge no matter what i do. When i plug it into USB it says drivers were not installed successfully Qualcomm CDMA Technologies MSM. EDIT: I was using an extended battery it must have died all the way so that the phone didnt even know what to do when it was plugged in. I put in my old battery luckily it had about 20% remaining. My phone charges fine usb and on the wall now but i dont know what to do a bout the extended battery thats not working anymore... anyone know if this was the batteries fault or the roms fault. Any way ican bring this extended battery back to life by installing some drivers. I just got it Last week itd be a shame to waste it. [SOLVE] Just uninstall and reinstall HTC Sync on your computer. Plug in USB and it should work fine. the drivers will be there. Charges fine now.
